Diapositiva PPT
- Dynamical system with a single stable fixed point, and two rather different time scales
- Small perturbations decay towards the fixed point in a simple way
- Perturbations above a threshold return back to the fixed point only after a large excursion (the excitation) in phase space
- The shape of this excitation is rather independent of the perturbation, as long as it is suprathreshold.
- During the excitation, the system is insensible to new perturbations
Ubiquitous in chemical, physical, and biological dynamical systems.
